Wood spurge Euphorbia amygdaloides 'Craigieburn'
ABOUT
The Euphorbia amygdaloides 'Craigieburn', also known as Wood Spurge, features striking foliage which is the main attraction of this variant. The leaves are elongated with a pointed tip and edge gently towards each other, giving them an almost cylindrical shape when viewed from the end. During the spring, the top side of the foliage showcases a vibrant chartreuse edge that accentuates their dark purple to almost black center. As the seasons change, these fiery edges fade, but the dark-toned leaves maintain their visual appeal, creating a dramatic contrast against the greener backdrop of many gardens. The plant also produces distinctive yellow-green flowers that are encased in long-lasting bracts, which add to its ornamental value. These flowers are small and grouped in structures known as cyathia, typical of the Euphorbia family. The Wood Spurge's overall appearance is bushy and full, which makes it a popular choice for adding texture and color to garden spaces.

- Toxicity
To humans
Wood Spurge, including the 'Craigieburn' variety, contains a white, milky sap that is toxic to humans. This sap is present in all parts of the plant and can cause skin irritation upon contact, including redness, swelling, and blisters. If the sap comes into contact with the eyes, it can cause severe pain and possibly temporary blindness. If ingested, the sap can cause symptoms such as a burning sensation in the mouth and throat, abdominal pain, vomiting, and diarrhea. Severe poisoning can potentially occur if a lot of the plant is consumed, leading to more serious symptoms and health implications such as difficulty breathing and changes in heart rate, although this is rare. It is important to handle Euphorbia with care and to avoid ingesting any part of the plant.
To pets
Wood Spurge is toxic to pets due to the milky sap contained in its leaves and stems. This sap can cause irritation and a burning sensation to your pet's mouth and lips if chewed or ingested. Other symptoms of poisoning may include vomiting, diarrhea, excessive drooling, and difficulty breathing if the reaction is severe. In some cases, the toxic sap may induce more significant effects such as changes in heart rate or weakness. It's essential to prevent pets from ingesting any part of the plant, as the consequences can be harmful and necessitate immediate veterinary attention.

During the growing season in spring and summer, it may require more frequent watering. Use lukewarm water and provide it slowly at the base of the plant, allowing it to soak in and reach the roots without waterlogging the soil. In general, you might give it about half a gallon of water every couple of weeks, adjusting the amount based on rainfall, temperature, and soil drainage.
- Light
Wood Spurge thrives best in partial to full sun. It prefers bright, indirect light or dappled sunlight, making it suitable for a spot where it can receive morning sun and afternoon shade. Avoid placing it in deep shade as this can lead to leggy growth and reduced vigor.
- Temperature
Wood Spurge prefers a temperature range between 50 and 75 degrees Fahrenheit. It can withstand minimum temperatures down to around 40 degrees Fahrenheit but should be protected from frost. The ideal temperature conditions are moderate, avoiding extreme heat or cold.
- Pruning
Prune Wood Spurge to maintain shape, control size, and remove spent flowers or any damaged stems. The best time for pruning is after the flowers fade in late spring or early summer. It's typically sufficient to prune once a year, cutting back stems to promote bushier growth and encourage more blooms for the following season.
- Cleaning
As needed
- Soil

- Life cycle
The wood spurge 'Craigieburn' (Euphorbia amygdaloides 'Craigieburn') starts its life cycle as a seed, which, once sown, requires a period of warmth, followed by a cold spell to break dormancy, a process known as stratification. Upon germination in early spring, the seedling emerges and develops into a rosette of leaves, beginning a period of vegetative growth. The plant matures and produces distinctive foliage, with the 'Craigieburn' variety having dark purple leaves with a narrow chartreuse edge. In the spring to early summer, the wood spurge produces greenish-yellow flowers, actually bracts, which attract pollinators and lead to seed formation after fertilization. The plant may also propagate vegetatively by rooting at stem nodes or from underground rhizomes, gradually forming dense clumps or spreading colonies. Throughout autumn and winter, the plant goes into a period of dormancy, reducing its above-ground presence, though the evergreen foliage may persist, before the cycle restarts with new growth in the spring.

Spring to Summer
The Euphorbia amygdaloides 'Craigieburn', commonly known as Wood Spurge, can be propagated most popularly by taking cuttings. This method is best carried out in late spring to early summer when the plant is actively growing. To propagate by cutting, a gardener should select a healthy stem and cut a segment about 3-5 inches (approximately 7.6-12.7 cm) long, making sure there are several leaves or leaf nodes present. The cut end should be dipped in rooting hormone before being planted in a mix of sand and peat for optimal rooting conditions. It is important to keep the cutting moist and in a warm environment with indirect light until roots have established, usually in a few weeks, after which it can be transferred to a more permanent location.
